Lessons Learned from Petya and WannaCry Ransomware

On May 12th, 2017, the first case of WannaCry ransomware was discovered and within a day, over 230,000 machines were estimated to have been infected in more than 150 countries.  The scale and speed of this attack left the industry stunned, but ransomware is not a new phenomenon.  Ransomware has existed in one form or another for fifteen years, and to date more than 350,000 different ransomware variants have been identified.  There are some fundamental differences in the way that WannaCry and Petya operate that make the spread of this variant more rapid and therefor dangerous than other variants before it.
